Swanson New Zealand Green Lipped Mussel Oil is nature's perfect solution for healthy, flexible joints. For hundreds of years, the native Maori population of coastal New Zealand has consumed the green-lipped mussel Perna canaliculus (also known as greenshell mussel) as a staple of their regular diet. Among modern nutritional scientists, the mollusk has gained a reputation as a "superfood" that not only helps maintain joint mobility, but also provides valuable nutritional support for the brain, eyes, skin and cardiovascular system. The health benefits of green lipped mussel are primarily attributed to its remarkable fatty acid profile, which features a roughly eight-to-one ratio of omega-3 to omega-6 oils. Green lipped mussels are raised in the clean, protected waters of New Zealand in accordance with some of the strictest quality standards in the world. Both the mussels and the water in which they're raised are monitored for bacteria, toxins and heavy metals. Recognized by the Blue Ocean institute as one of the top two "eco-friendly seafoods" in the world, the mussels are a truly sustainable nutritional resource, grown with no pesticides, herbicides or artificial feeds. Swanson EFAs New Zealand Green Lipped Mussel Oil averages approximately 37.5% omega-3 fatty acids, including 21.6% EPA and 8.4% DHA. Our softgels deliver 50 mg of green-lipped mussel oil in an olive-oil base.
